This Sango Occupied Japan child's mug or cup is just over 3" high by 3" diameter at the rim. It's decorated with sprays of violets and has the phrase "For a Little Shaver" printed in gold at the top of the mug. The underside is marked "Sango China, Made in Occupied Japan". Very, very slight wear to the gold ring at the upper rim, otherwise excellent condition.
The term "little shaver" is often thought to refer only to boys but actually in the old days it was used to refer to small children of either gender. I'm unsure whether this mug was meant as a toy shaving mug (it does have the right shape if not decoration) or as a child's drinking cup.
